.had to the accompanying drawing in which like characters designate corresponding parts in all the views. Y

Figure 1 is a plan of an electrical conduit outlet box provided with my invention, the cover for such box being open. Fig. 2 is a cross-sectional view of the box and cover therefor provided with my invention. Fig. 3 is a fragmentary view illustrating the bolt of the lockin rear elevation, contigu-l ous parts of the box and cover being also shown. Fig. 4 is a detail view of the bolt of the lock. Fig. 5 is an, inverted view of the detached handle. f

1 is the conduit outlet box, here shown as rectangular in form in top plan and as provided with` extensions at 1ts ends having nipples 2 for connection with conduits inclosing lelectric wires havingan outlet in the box 1 or connected to electrical appliances inthe box 1. 3 is a cover for the box 1, the cover being hinged to the rear side of the box at 4. Y

The lock for holding the cover in its closed position comprises a bolt located on the inside'of the box in such position as to occupy a minimum space'so as not to interfere with electrical appliances or other contents of the box 1, and a handle located on the cover preferably formed of sheet metal. The bolt 5 consists of a iat bar or plate havin its major or intermediate part slidable aong the inner face of the cover 1. The front end of the bolt depends from said major or intermediate part 'substantially perpendicular thereto and terminates in a portion 6 disposed substantially in parallelism with the major part of the bolt and forming a pawl or latch which interlocks with a shoulder 7 on the inner face of the front side of the box 1. Said portion 6 also coacts with an outwardly'inclined 'surface 8 on the box above said shoulder for causi ing the bolt 5 to latch as the cover appreaches its closed position. The holt 5 is formed with a lengthwise slot 2T through whlch proJects means fixed to the cover for supporting the bolt 5, said means being here .shownv as in the form of a pin or rivet 10 having a head 11 slidably engaging the lower face of said bolt.

12is a handle for the bolt and also for the cover, vs aid handle vhaving a'stem 13 extending through a slot ltformed in the cover 3, and extending at right angles to the front and rear sides of the box, said stem 13 extending through a hole 15 in the bolt 5 vand being fixed to the bolt 5 in any suitable manner. The handle 12 is also formed with a base 16 slidably engagingthe upper face of the cover and large enough to cover the slot 14 in all positions of the handle 12. The bolt 5 is forced to its operative position by a spring 17 formed of a single piece of wire secured at the opposite ends at 18 to the cover, the intermediate portion thereof being bowed and interposed between the inner face of the cover 3, and the offset lug 19 atthe rear end of thebolt 5, said lug extending downwardly and then rearwardly from the rear edge of the major part of the bolt, and the intermediate ortion of the sprlng engaging said edge. referably the ends ofthe spring `17 are secured to the cover by widely spaced pins depending from the inner face of the cover and provided with heads forming'the lower sides of recesses between said inner face and heads for receiving the spring.

This lock is particularly simple in 4construction occupies minimum space, and the spring thereof is durable and easily replaceable when broken.

l/Vhat I claim is:

1. The combination with a box, a cover hinged to the box and having a slot, a bolt formed from a flat plate and having its major or intermediate part enga-ging the underside of the cover, and its end portions offset therefrom, the front end portion depending from the major part of the bolt and terminating at its lower end in a pawl or latch for engaging the box, the offset rear endv of the bolt forming a recess between the same and the underside of the cover, a bowed spring secured at its ends to the cover and having 1ts intermediate portion located in the recess and shouldering against the 'iov bolt, and a handle connected to the major part of the bolt and including a stem extending through the slot in the cover and a head mounted on the stem and slidable on the outer face of the cover, substantially as and for the purpose described.

2. In combination in an outlet box, a side wall having a nose at the outer marginal portion thereof presenting a shoulder and an outwardly inclining face, a cover pivotally mounted adjacent the outer edge of.A

the opposite side wall, a bolt formed by a flat plate having its major part disposed parallel to the under face of the cover and in contact therewith, said, plate having at its rear end an offset rearwardly extending lug, and at its opposite end a part extending substantially perpendicular to the major part and terminating in a portion. disposed substantially in parallelism with the major part and coacting with said shoulder and inclining face, headed members secured to the cover in rear of the plate and spaced widely apart and providing abutments having receiving recesses, a bow spring held at its ends in said recesses and having its intermediatel portion in engagement with the rear end of the majorpart of said plate and confined between -the lug thereof and the opposing portion `of the cover, and means for holding the bolt in position including a knob connected to the bolt and having a part accessible on the upper side of the cover, substantially as and for the purpose described.

3. In an -electric conduit outlet box, the combination with a box proper, 'having one side provided with a shoulder, and a surface above the shoulder inclining therefrom toward the outer surface of the box proper, of a cover hinged to the opposite side of the box proper and provided with a slot extending at substantially right angles to said sides of the box proper, a bolt consisting of a flat bar having a flat upper face slidably engaging the flat inner face of the cover, the bolt being provided with a lengthwise slot, the front end of the bolt being extended downwardly and coacting with said shoulder and inclined surface, and the rear end of the bolt .having a lug extending downwardly and then rearwardly from the rear surface of the bolt, a spring having its intermediate portion held between the lug and the opposing inner face of the cover and coacting with said rear surface of the bolt, a handle covering the first-mentioned slot and slidable on the outer face of the cover and having a stem guided in said first-mentioned slot and fixed to the bolt at a point spaced apart from the slot in said bolt, a pin having one end fixed to the cover and its other end passed through the slot in the bolt and provided with a head slidably engaging a lower surface of the bolt and spaced apart means projecting from the inner face of the cover and supporting the ends of the spring.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county 4of Onondaga, in the State of New York,
